The Philips MR system uses 3D cine phase contrast angiography for 4D Flow imaging. The Hadamard method is used for the bipolar gradient and it is possible to reduce the load on the gradient system and the influence of the eddy current, as well as shorten the imaging time. Compressed SENSE can be used for 4D Flow and the imaging time can be significantly reduced while the image quality and SNR is maintained. The k-t PCA provided by GyroTools is also available and can make use of a high acceleration factor.
